Pressure Distribution Over a Clark Y-H Airfoil Section with a Split Flap

An investigation was made in the N.A.C.A. 7- by 10-foot wind tunnel of the distributions of air pressure over one chord section of the Clark Y-H airfoil with a split flap. The results obtained are given in the form of diagrams showing the chordwise distribution of pressure on both airfoil and flap and as plots of calculated aerodynamic coefficients for both airfoil and flap.
